Letters .Patent No. 90,297, dated .May 18, 1869.

IMPnovnn RAmWAY-CAR SEAT.

The Schedulexeferred in these Letters Patent and znaking part of the'same- LINGs, vof Wilmington, county ot' 'New Castle, State4 ofDelaware, have invented an Improvement in Seats for Railway-Cars, Sac.;'and we do hereby declare the following to be a full, clear, and exactdescription of the same.

Our invention relates to an improvement on the carseat for which LettersPatent were granted to /us on the 8th day of December, 1868; our presentinvention consisting of devices, fully desclibed hereafter, for soadjusting the seat that it may be depressed in front or at the rear, ormay be in a horizontal position. l

In order to enable others familiar with mechanism of this class to makeand apply our invention, we will now proceed to describe itsconstruction and operation, reference being had to the accompanyingdrawing, which forms a part of this speciicatiomand in which- Figure lis a vertical sectional view of our improved seat for cars, duc; l

Figure 3, an inverted plan view; i

Figure 4, a detached sectional view, on the line 3 4, tig. l; and lFigure 5, a sectional perspective view, lillustrating a portion of ourinvent-ion. l i

Similar letters refer to similar parts throughout the several views.

The frames A and A', of the chair, are in the presentinstancc of castiron, and are connected together, near the top, by three rods, ,a, andb, the latter rod, which is attached to the centre oi' each side frame,

being situated slightly above, but midway betweenthe rods a and a'. v

Two plates, B and B, are fitted loosely to the rod b, and are connectedtogether by a senlicircular strip 0r plate B", which passes partlyaround, but is free from contact with the rod, the whole forming a rigidmetal frame, which can turn freely upon but is prevented from movinglodgitudinally on the saidrod b,

On the inner sides of' the plates l5 and l are grooves, to which areadapted lugs c c, formedbn the lower edges ot' two plates, F` and F',which are "secured to thelopposite sides ofa box, H, the latter formingthe lower portion of the seat of thechair,. whici1, when thus attachedto the plates B and B', can be` moved thereon longitudinally, to thelimited extent required in adjusting the back of the seatto,dii'lerent,angles, as fully described in our aforesaid patentotDecember 8, 1868. ,g ,d

In our former patent, the seat, although 4permitted to slidelongitudinally between the/'side frames, was always maintained in ahorizontal position. By the employment of ceitaiu. devices, however,which we will Figure 2, a section of the same, on the line .12,

... -9 4. I proceed'to describe, we are now enabled to adjust the seat,as well as `the back, to' any desired angle.

A curved plate 0r yoke, J, passes beneath the rod b and plate B", andover the rods a and a', its curved ends partly embracing' the latter, asbest observed in fig. 1.

tndinal slot, f, of the plate B, and forms a sleeve, li, which islarranged to slide upon the rod b, and at a point directly beneath this.sleeve is a nut, i, having threads corresponding to those of a screw,L, which passes through and is arranged to turn freely 1n the frame Aotthe chair, but which is prevented from4 moving longitudinally in thesame by its collars e c. (See iig. 2.)

To a pin, l, at one end of the yoke J, is hung a toothed cannlll, whichgears in to a rack, g, secured to the under .side of the seat H, and atthe opposite end of the yoke is hung asimilar toothed cam, M,

which also gears into a rack, g, ofthe seat.

As the seat is arranged to have a sliding motion be? position of thesliding seat, the said cams are always iu gear with,the rac-ks.

The seat H is in eiiect pivoted to the rod b, and rests upon the cams Mund M', its inclination being determined entirely by the latter, whichare so ar ranged, that when one cam is elevated, the other is depressed,as seen in iig. 2.

When the yoke J is caused to slide upon the rods a, a', and b,byoperating the screw L,'the toothed cams will also be caused totraverse the racks g, and to turn upon their pins l, -one ot' the camsbeing raised as itis turned, and thus elevating that edge ofthe seat towhich it is in nearest proximity, while the opposite cani will becorrespoinlingly lowered, and will Ipermit the proper depression Vof theopposite edge of the scat.

This will be 'illustrated by referring to iig. 5, and supposing that theyoke J is being moved in the c irection ot' the arrow, by a propel'operation ot the screw lhe racks being sttitionary, the cams will bothturn, and in the same direction; but owing to the manner in which theyare adjusted in relation to each other, the edge x ofthe seat will beelevated by the calnM",

while the cani M will be so operated as to permit the opposite edge xot' the seat to descend.

It will be evident that on reversing the motion o:` the screw, and thussliding the yoke in a diiferent direction, the action ot' the cams willhe also reversed.

Stops z z, at the opposite ends ofthe slot j; of the plate Bierearranged to arrest the yoke J, in order A vertical arm of thisvokefpasses through a longitoprevent the latter from being moved to suchanextent as to show the toothed cams out of geur with the racks g g;

When the sent has been adjusted to a, horizontal position, or to vanydesired angle, and the motion of the cams @ils stopped, the latter willform eieetual rests for the scl t, and will prevent it from tilting.

Althou.,h we prefer to use the above devices in connection w th a. hzu'rhaving zmndjnstable back, asilescribe v in Iour fermer patent, yet itwill be evident that they can e used independent-ly ofthe sume, inwhichv case the seat, not reqniringa. sliding motion, can besecnredrdirectly to the plates B and B, and the racks lg g can be madeof a width corresponding to that of the toothed segments.

We claim as our invention, and desire to secure by Letters Patent;

1. Theseut H, pirated directly or indirectly to the rod b of the frame,and having racks', g g, adapted t toothed eams MM', by the movementofwhich, through the medium of the devices herein described, or any'equivalent to the saine, the said seat H may be adjusted as set forth.

2. The sliding yoke J, ezurying the toothed cams M rand M', andcontrolled by the screw L, in lombinntion with the r-.ieks g g beneath-the seat H, the whole being arranged and operating substantially as andfor the purpose herein set forth:

In testimony whereof, we have-signed our names to this specieation, inthe presence of two subscribing witnesses.
